The learning curve for radiofrequency ablation of tachyarrhythmias in pediatric patients. Participating members of the Pediatric Electrophysiology Society. [link]Paper  abstract   bibtex   
The results of radiofrequency ablation for treatment of supraventricular tachyarrhythmias have been reported to improve with increasing experience; however, the precise nature of the learning curve in children is unknown. From November 1990 to October 1993, 1,546 consecutive procedures from the Pediatric Radiofrequency Ablation Registry were categorized into deciles based on number of prior pediatric procedures at the submitting institution. Negative exponential models were tested for strength of relation between volume of prior experience and 4 measures of outcome: success rate, complication rate, fluoroscopy time, and procedure time. Negative exponential curves described the experience-outcome relations well (r = 0.81 to 0.97). Learning rates were most rapid for successful ablation of left free wall accessory pathways, and slowest for right free wall pathway ablation. These models suggest that, given enough experience, procedural success rates \textgreater 90% (regardless of pathway location) and fluoroscopy and procedure times averaging \textless 40 minutes and 250 minutes, respectively, can be achieved in pediatric patients.
